Application filed January To all whom it may concern:

Be it known that I, WVILLIAM S. I-IUNKINs, a citizen of the UnitedStates of America, residing at Los Angeles, California, have invented anew and useful Pin Tube, of which the following is a specification.

My invention relates to a so-called pin tube, construction and to acombined pin tube tab end which may be conveniently secured to anygarment. The object of the invention is to provide a construction bywhich a complete tab end including a tube may be economically producedin large quantities so that the same may be made and sold as units foreasy attachment toany garment by the purchaser.

In the accompanying drawing:

Figure l is a front View partly broken away and showing my invention asit would appear in use on a garment.

Figure 2 is a view of the inside of the tab with the tube securedthereto.

Figure 3 is a section on the line 06'Q3 Of Figure 2.

Figure 4: is a perspective View of the pin tube itself.

1 represents a rolled up sheet metal tube having a flange 2 along oneside thereof. 3-3 are spurs formed integrally with the flange 2. 4 is ashort strip of fabric with its side edges folded in as at i P so as tomake the width of the fabric strip conform substantially to the lengthof the tube 1. The tube is attached to said short strip of fabric bycausing the spurs 3-3 to penetrate the same as shown in Figure 2. Thespurs preferably penetrate and are turned down on the two thicknesses offabric formed by the aforesaid side folds, so that greater security willbe provided on the one hand, while on the other hand, the spurs and theoverlying part of the tube flange give permanence to said edge folds.The articles may be made up and vended in the form shown in Figure LOSANGELES, CALIFORNIA.

TUBE.

2. When a purchaser desires to apply one of these tabs to a garment, thestrip is folded transversely around the tube portion 1 so that thelatter will stand in the b ight of said fold as shown in Figure 1. Thetwo ends of the strip are then secured to the garment 5 by means ofstitches or other convenient fastenings.

From the foregoing it will be seen that said articles may be veryrapidly and eco nomically produced in a form which lends itselfadmirably to packing and transportation. The form of the fastening 3 maybe modified at will, the form shown being preferable.

I claim:

1. A pin tube tab end comprising a short strip of fabric, a sheet metaltube extending across an intermediate part of the same from edge toedge, a flange extending lengthwise of said tube, fastening devicesformed integrally with said flange between the ends thereof, saidfastening devices penetrating said fabric and being bent into holdingengagement therewith.

2. A pin tube tab end comprising a short strip of fabricfolded along itsside edges, a sheet metal tube extending across an intermediate partthereof from edge to edge, a flange extending lengthwise of said tubeand integral fastening devices on said flange, said fastening devicespenetrating the side folds of said strip and bent into engagementtherewith to hold said fabric against said flange.

3. A pin tube tab end comprising a short strip of fabric having eachside edge folded in to form a double thickness of fabric, a pin tube ofsheet metal having a flange with spurs formed thereon, said spurspenetrating the two thicknesses of fabric at each side edge of saidstrip and being bent to secure said tube to said strip and to hold downsaid folds.
